Get pricegenerator (HRSG). Unlike gas turbines or microturbines, steam turbines do not directly consume fuel. Rather, the fuel driving the process is the fired boiler or plant equipment that produces heat for the HRSG (e.g., a gas turbine). Table 1. Summary of Steam Turbine Attributes for CHP. Size range. Steam turbines are available in sizes from under

Get priceJan 09, 2013 · FGR is the process by which exhaust gas is introduced into the combustion-air stream prior to a burner. Flue gas also is relatively cool (300°F to 550°F, depending on the design of the boiler and whether there is a feedwater economizer) with respect to flame temperature, and flue gas has little oxygen from the combustion process.

Get pricefrom this operation. Second operation is when exhaust gases expands in the gas turbine it enters into the waste heat recovery boiler so that the water which is presented in the boiler gets converted into the steam. This high pressure and temperature steam expand in the steam turbine so that the power will be obtained from the steam turbine.
